Discuss your dissection of the components of the endocrine system of the fetal pig by doing the following: a. Describe the endocrine organs that are located in the throat region (e.g.‚ function and appearance). Thyroid - small dark brown‚ pink gland in the trachea. Its function is to regulate metabolism and secrete

area of LOW to High solute concentration. 3. Because water moves toward the HIGH concentration of solutes. 4. We know the pressure will increase in the albumin beaker because it is more impermeable than glucose. The pressure in the beaker containing the albumin increased despite the increased concentration of glucose because albumin has a much greater molecular weight. Activity 4 1. Increasing the size of an opening allows more space for movement. For example‚ the more you open the nozzle

person would be quite tired/exhausted‚ but with the correct fitness exercises to work on cardiovascular endurance it would get easier and easier to run such an event. The reason your cardio performance can be improved is because the heart is a muscle‚ and like all other muscles in the body if you keep working it it will adapt to the workload given. This allows us to have direct control of how healthy one of the most important systems in our body is. Your body will also adapt to running the aquathon

Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

Predict Question: Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction velocity will be the same in both fibers. Stop & Think Questions: 3. Note the difference in time between

Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
